 About
 =====
 
 [Nodel](http://nodel.io) is a digital media control system for museums and galleries.
 
-Nodel is typically used to control digital media devices in galleries, museums, corporate meeting rooms and digital signage.
+Nodel is typically used for the control, monitoring and scheduling of digital media devices. With a design focused on galleries, museums, corporate meeting rooms and digital signage.
+
+An active instance of Nodel can manage any number of integrate media devices, or assistant tools (schedulers, monitors, clusters) to form a coherent and manageable group of *nodes*.
+
+These nodes are discoverable from other active instances of Nodel on the network, by which a series of user specified *bindings* allows the seamless propagation of remote actions and events between a group of nodes.
+
+The nodes are written utilising a Python (Jython) API, examples of which are available on the [recipes](https://github.com/museumsvictoria/nodel-recipes) repository.
+
+There's also a fully featured web interface for configuration of nodes, including an in-line editor to encourage most activities to take place within the platform.
